Title: Which gti turbo?
Post by: benny1234black on 18 November 2010, 16:51
Hi all my name is Ben I have decided to join this forum after looking around for a good few months!

Anyway, as it says above I am not sure which gti turbo to get i.e. what year or model?

I know that the newer aum does come with the k03s but the older ones are much cheaper to buy and I may even replace the turbo anyway?

A little advice on this would be great I know it is a broad question but which would you buy if the funding is not the issue?  (no funding yet for me :cry:)

I would say a 2001 onwards AUM engine mate personally.. I also believe they have KO3s turbo's already  :wink:

You could buy my 1998 AGU with ko3s and lots of mods with 236 bhp and 268 ftlbs...... :grin:

Thanks for all the replys!

I am stick stuck on deciding to go agu and fit a k03s or just get a aum with already fitted.   With ignoring the turbo differences as I would fit one anyway on the agu.

Are there any main advantages on getting an aum or agu?

Coilpacks tend to be "weaker" on the AUM (i.e. they fail more often). Also the AUM has a secondary air injection (SAI) system which can be prone to faults, and also has a more complex breather pipe system for the oil vapour but i'd recommend stripping this all out out and fitting a catch can anyway.

Other than that you get the advantage of having a KO3S already bolted on and a stage 1 remap should see you right to 210bhp.

The AGU has a better flowed head IIRC than the AUM but this won't come into play until you start going beyond stage 2 mods IMO.

I drive an AUM and have no other golf to compare it to but these are the thoughts off the top of my head from being a member on here for the past couple of years.

At the end of the day i would buy whatever comes along thats in good nick with decent milage etc but if you go to look at an AGU bear in mind budgeting for the KO3S conversion on top of the buying price.

HTH

Good advice from Waffs there.
If you want to do a K03s convertion on a AGU i would make shoe you facter in the cost thats involved to do this. and if its really worth it if you can get a golf with it alread on. Also somthing eles to also consider is some of the newer MK4 had the 6 speed gear box along with the ko3s.

Nope  :smiley:
When i was thinking of ever changing mine or to spend the time swaping Turbos i looked around at what was out there. Anny was my idear but when i relised there where standerd golfs around with the K03s and 6 speed which where not Annys, the hunt was on. Found about 6 in the month i was looking around :)

Yep VWPrime is right, they do exist but were fairly rare. The AUM was never fitted with a 6-speed but the AUQ's were. The AUQ engine code is found in the anni's but was also found in some very late "normal" GTi models  :wink:

You could just buy a AGU with a ko3s already fitted and save cash that way. The 6 speed box isn't as well suited to the engine as the 5 so I've been told.....

Your looking at 250 for a second hand ko3s and 350 for a turbo swap and map to suit thats if you go with the agu mate.
